Dark Wikipedia (SKYY's Version)

Haven't tested it thoroughly yet, but it looks fantastic!

I actually thought the bluish-green boxed were intentional, until I read that they weren't. Nonetheless, I really like them, they provide a means of immediate contrast for cognitive separation. Overall, this script works very well for me. My only concern is that on chemical/molecular pages, I can't see the print inside the box with the graphical representation of the molecule in question. Beyond that, I am not sure what else I may be missing. I think you should first concern yourself with visibility, and let aesthetics follow later.

An ad hoc solution to your h2 problem could be replacing "h2" with "tr > th > h2" (see http://blog.userstyles.org/?p=45 for details). As far as I can tell it'll only 'trigger' on the front page where you want it. As for the id="Today.27s_Featured_Article" - it doesn't seem to apply to the h2 element, so I wouldn't figure that could work...
